Commentary: If Singapore decides to invest in nuclear energy, floating power plants deserve a closer look

In any case, nuclear power requires strict safety and regulatory oversight, involving multiple organisations.

Classification societies evaluate the safety of new vessels and have begun issuing comprehensive rules for floating SMRs. 

Together with industry stakeholders, they established the Nuclear Energy Maritime Organisation last year to support national and international regulatory efforts. The International Maritime Organization, responsible for marine pollution prevention and vessel safety, and the International Atomic Energy Agency are also working on floating SMRs and nuclear-powered ships, given the increasing climate change-driven interest in them.

WORTH SERIOUS CONSIDERATION

Selecting a safe and economically viable site would be crucial. 

Deeper waters are preferable for cooling purposes and limited environmental impacts, but a site like Changi could pose risks due to its proximity to the airport and potential airplane accidents affecting the plant. Marine traffic restrictions and protective measures, such as security protocols, would be necessary. 

Proximity to industrial plants on Jurong Island in demand of heat or steam could enhance economic viability, making the nuclear cogeneration plant(s) more cost competitive, and desalination is another option.

If Singapore decides to pursue nuclear power, floating SMRs warrant serious consideration. They offer distinct advantages in location selection, deployment flexibility, absence of landscaping requirements, and potential integration with industrial processes. However, economic feasibility, safety, regulatory requirements, and environmental impacts must be thoroughly evaluated to determine whether they align with Singapore’s long-term energy strategy.
